Oversized backup rolls production inspection

Backup rolls production inspection Mainly detects the runout value, roughness and size, roll neck and roll body hardness. The roll necks and joints were inspected. At present, the keyways at both ends have not yet been processed. After processing, UT, MT testing, hardness testing and final dimensional accuracy testing will be carried out.

The essence of the backup rolls is to support the work roll. By contacting the work roll with the workpiece, the diameter of the work roll can be reduced and the stiffness of the work roll can be enhanced. The backup roll is an important component in the rolling mill. It is used to support the work roll or the intermediate roll to prevent the work roll from deflecting and deforming, which will affect the output and quality of plates and strips.
